(54) | IMPLANTABLE DEVICE AND TISSUE ANCHOR |
(57) The invention provides an implantable electrode lead for facilitating electrical
stimulation of tissue of a patient, the electrode lead comprising a lead body having
a distal end; an electrode attached to the distal end of the lead body, the electrode
comprising a plurality of stimulation elements formed of an electrically conductive
material; and at least one insulative element formed of an electrically non-conductive
material; wherein the stimulation elements and the at least one insulative element
are joined together to form a stacked column of alternating stimulation and insulative
elements; a plurality of electrically conductive wires extending through the lead
body, each wire coupled to one of the stimulation elements; and a tissue anchor configured
to facilitate anchoring the electrode to tissue of the patient, wherein each of the
stimulation elements comprises a body having first and second ends; and each of the
at least one insulative elements comprises a body having first and second ends that
are respectively configured to interconnect with the second and first ends of the
body of one of the stimulation elements.
